stop() method on AudioScheduledSourceNode schedules a sound to cease playback at the specified time. If no time is specified, then the sound stops playing immediately.

每次调用 stop() on the same node, the specified time replaces any previously-scheduled stop time that hasn't occurred yet. If the node has already stopped, this method has no effect.

注意： If a scheduled stop time occurs before the node's scheduled start time, the node never starts to play.

句法

AudioScheduledSourceNode.stop([when]);

参数

当 可选: The time, in seconds, at which the sound should stop playing. This value is specified in the same time coordinate system as the AudioContext is using for its currentTime attribute. Omitting this parameter, specifying a value of 0, or passing a negative value causes the sound to stop playback immediately.

返回值

undefined

异常

InvalidStateNode: The node has not been started by calling start() .
RangeError: The value specified for 当 为负。

范例

This example demonstrates starting an oscillator node, scheduled to begin playing at once and to stop playing in one second. The stop time is determined by taking the audio context's current time from AudioContext.currentTime and adding 1 second.

context = new AudioContext();
osc = context.createOscillator();
osc.connect(context.destination);
/* Let's play a sine wave for one second. */
osc.start();
osc.stop(context.currentTime + 1);
